This is only the first of many announcement streams for NijiFes, it took like 3 streams last year to announce that any of the EN members was going to participate. I’m going to assume more are in the pipeline that would be announced in streams in the future, although the official EN account not saying anything in terms of more future announcements vs the official JP account might be either EN account being dumb as usual or we really only have this small ass roster, if the latter is true, damn that is a shit EN roster.
EDIT: Alright shu not being there means this roster is gonna be shit, can't even have one of the popular in JP luxiem member join nijifes, one of the biggest events in niji
